Don't use a strip-type thermometer, which you hold on your baby's forehead, to check your baby's temperature. Strip thermometers only show the temperature of your baby's skin, not her body. It's also best not to use an old-fashioned, mercury-in-glass thermometer.
If your prawns are smaller, spread a piece of aluminum foil or banana leaf on the grill first, then place prawns on top. Or skewer the shrimp with satay sticks (if wood, soak in water first). Baste the prawns the first time you turn them with a little of the leftover sauce. Grill 3 to 5 minutes each side. Prawns are done when the flesh turns from translucent to pinkish-white (and the shells turn a very attractive bright pink).
Generously oil the grate or hinged fish grilling basket. Brush both sides of the fish with oil or melted butter. Place the fish on the hot grate directly over the heat and grill until the skin is dark and crisp and the flesh is cooked through to the bone, 6 to 15 minutes per side, depending on the size of the fish. Turn the fish, using a long spatula or by inverting the basket, and cook the other side the same way.
